从另一个流中检索 HLS 数据并将其推送到 rtmp 服务器答案

【问题描述】：

我一直在从事一个需要能够动态推送到 2 或 3 个其他频道的项目。我测试了几个场景，我的最后一次尝试如下：

流服务器

worker_processes auto;
rtmp_auto_push on;
events {}
rtmp {
    server {
        listen 1935; # Listen on standard RTMP port

        application live {
            live on;
            hls on;
            hls_path /www/tmp/hls;
            hls_fragment 10s; # default is 5s
            hls_playlist_length 5m; # default is 30s
            # once playlist length is reached it deletes the oldest fragments

            # authentication
            # on_publish => some other server
            # on_done => some other server
        }
    }
}

http {
    server {
        listen 8080;

        location /hls {
            types {
                application/vnd.apple.mpegurl m3u8;
                application/octet-stream ts;
            }
            root /www/tmp;
            add_header Cache-Control no-cache;

            # To avoid issues with cross-domain HTTP requests (e.g. during development)
            add_header Access-Control-Allow-Origin *;
        }
    }
}

然后强制另一台服务器读取该服务器创建的 hls 内容。我尝试使用 node-media-server 和 nginx，但都没有真正的解决方案，这是我对 nginx 的尝试：

events {}
rtmp {
    server {
        listen 1935; # Listen on standard RTMP port
        chunk_size 4000; 
        # ping 30s;
        # notify_method get;

        # This application is to accept incoming stream
        application live {
            live on; # Allows live input
            deny play all; # disable consuming the stream from nginx as rtmp

            hls on; # Enable HTTP Live Streaming
            hls_fragment 3;
            hls_playlist_length 10;
            hls_path /www/tmp/hls;  # hls fragments path
                        
            # MPEG-DASH
            dash on;
            dash_path /mnt/dash/;  # dash fragments path
            dash_fragment 3;
            dash_playlist_length 10;    
            push => another rtmp server;
        }
    }
}

http {
    server {
        listen 8080;

        location / {
            root /www;
        }

        location /hls {
            types {
                application/vnd.apple.mpegurl m3u8;
                application/octet-stream ts;
            }
            root /tmp;
            add_header Cache-Control no-cache;

            # To avoid issues with cross-domain HTTP requests (e.g. during development)
            add_header Access-Control-Allow-Origin *;
        }
    }
}

如果您知道任何其他选择，请告诉我或有任何其他建议，谢谢

【解决方案1】：

你想这样做如下：

Client -----> Nginx -------> Server
         (Stream 1/2/3)    (Stream 2)

你不应该让另一个服务器从 Nginx 读取Stream 2，你应该使用FFmpeg 作为客户端来执行此操作：

Client -----> Nginx -----> FFmpeg  --> Server
         (Stream 1/2/3)             (Stream 2)

为此，请运行如下命令：

ffmpeg -f flv -i rtmp://ip/live/stream2 -c copy -f flv rtmp://server/live/stream2

所以你可以从 Nginx 读取任何流到另一台服务器。

如果您希望Server 执行此操作，可以使用SRS/Ingest，它派生一个FFmpeg 进程将流拉到SRS
